Abstract
e16333 Background: Undifferentiated carcinoma of the pancreas is a rare and highly aggressive form of pancreatic cancer, characterized by its low degree of cellular differentiation. The prognosis for this condition remains poor, with median survival times typically not exceeding one year. While existing research indicates that treatment at academic institutions may lead to improved survival outcomes compared to non-academic settings, there is scant research on this topic in the context of undifferentiated carcinoma of the pancreas. Addressing this research gap, this study analyzes data from the National Cancer Database (NCDB) to compare long-term survival rates between patients treated at academic institutions and those at other facilities. Methods: The National Cancer Database (NCDB) was used to identify patients diagnosed with undifferentiated carcinoma of the pancreas from 2004 to 2019 using the histology code 8020 as assigned by the Commission on Cancer Accreditation program. Kaplan-Meier, ANOVA, and Chi-Square tests were performed. Data was analyzed using SPSS version 27 and statistical significance was set at α = 0.05. Results: In this analysis of 284 patients, 124 (43.7%) received care at academic centers, while 160 (56.3%) were treated at non-academic institutions. Individuals treated at academic centers had a significantly extended mean overall survival of 27 months compared to 13.9 months for those treated elsewhere (p < 0.05). Additionally, patients at academic centers were more likely to be insured, undergo surgical interventions, receive chemotherapy, and be initially diagnosed at a different facility (p < 0.05). Conversely, patients at non-academic centers were more likely to be white, live closer to their care facility, and exhibit greater metastatic regional lymph nodes (p < 0.05). However, there was no significant association between treatment at academic centers and variables such as median income, cancer grade, and Charlson-Deyo Comorbidity Index (CDCI) (p > 0.05). Conclusions: This study revealed that individuals with undifferentiated carcinoma of the pancreas receiving treatment at academic centers exhibit a significantly improved overall survival rate compared to those treated at non-academic centers. This disparity in survival rates might be attributed to the higher prevalence of chemotherapeutic treatments and surgical interventions at academic institutions. While these observations are based on correlational data, they underscore the necessity for further investigation to establish causality.
